Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528332, here are decompositions:
- 5 + 31528327 = 31528332
- 19 + 31528313 = 31528332
- 41 + 31528291 = 31528332
- 53 + 31528279 = 31528332
- 103 + 31528229 = 31528332
- 163 + 31528169 = 31528332
- 181 + 31528151 = 31528332
- 211 + 31528121 = 31528332
Showing the first eight; more decompositions exist.
